SQL Server and LocalDB compete in the relational database management systems category. SQL Server holds the upper hand due to its extensive enterprise features and scalability options.
Features: SQL Server provides programmability, scalability, and integration with Microsoft products, making it suitable for enterprise-scale solutions. LocalDB offers essential database functionalities with simplicity, suitable for lightweight local development and prototyping.
Room for Improvement: SQL Server can improve on its licensing costs, integration with other platforms, and scalability for large datasets. LocalDB could benefit from enhanced functionalities, better integration capabilities, and improved deployment ease.
Ease of Deployment and Customer Service: SQL Server supports multiple deployment options, including on-premises, public cloud, and hybrid models, with robust Microsoft support. LocalDB is typically deployed on-premises or in the cloud for development, with adequate online support but limited direct options.
Pricing and ROI: SQL Server pricing reflects its feature richness; it may be expensive, but the ROI justifies the cost for large enterprises. LocalDB is cost-effective, being free, making it ideal for development and small applications but lacking advanced features for high ROI in extensive deployments.

SQL Server is a relational database management system (RDBMS) by Microsoft. The product's main purposes are to store data and retrieve it as requested by other software applications - on the same computer or on another computer across a shared network. The solution is built on top of Structured Query Language (SQL), which is a standardized programming language used for relational database management.
The product is tied to Transact-SQL (T-SQL), which is an implementation of SQL from Microsoft that adds several proprietary programming extensions to the standard language. SQL Server is built similarly to other RDBMS products, as its structure is a row-based table that connects related data elements in different tables to one another. One of its most important components is the SQL Server Database Engine, as it controls data processing, storage, and security. Beneath the Database Engine is the SQL Server Operating System, which is used for memory and I/O management, locking data to avoid unneeded upgrades, and job scheduling.
The solution has four editions with different sets of services and tools. They include:
The first two are available for free and are typically utilized by smaller companies, as they work with fewer functions and storage. The second two editions are generally used by bigger organizations and enterprises and offer more features.
The solution has several functions through which users can facilitate different data-related processes. These include:
SQL Server Services
SQL Server has a wide range of add-on services that provide additional benefits beyond database management. These services include:
SQL Server Benefits
The solution has many benefits for users. These include the following:
Reviews from Real Users
A president at a consultancy evaluates SQL Server as a veteran solution with critical log shipping feature.
Harkamal S., a user at a manufacturing company, rates SQL Server with a high mark because it is a stable, scalable, and easy-to-deploy solution that pretty much covers everything.
